This error occurs during complications of Vyper contracts from brownie. Only happens when the vyper version used is >= 0.3.6, works fine when I set it to 0.3.3. No idea of what's going on, could anyone see what's wrong here? Tyvm!

this was a brownie issue which was fixed as of 0.19.2 eth-brownie/brownie#1623 -- please upgrade your brownie version to latest and reopen if there is still an issue
